Rotational states of an asymmetric vortex pair with mass imbalance in binary condensates
Alice Bellettini, Andrea Richaud, Vittorio Penna
We consider massive vortices in binary condensates, where the immiscibility condition entails the trapping of the minority component in the vortex cores of the majority component.…
Gas-to-soliton transition of attractive bosons on a spherical surface
A. Tononi, G. E. Astrakharchik, D. S. Petrov
We investigate the ground state properties of bosons with attractive zero-range interactions characterized by the scattering length and confined to the surface of a spher…
Exact results for heavy unitary Bose polarons
Nikolay Yegovtsev, Grigori E. Astrakharchik, Pietro Massignan +1
We consider the problem of unitary Bose polarons, i.e., impurities interacting via a potential with infinite scattering length with a bath of weakly interacting bosons. We provide…
Conformal maps and superfluid vortex dynamics on curved and bounded surfaces: the case of an elliptical boundary
Matteo Caldara, Andrea Richaud, Pietro Massignan +1
Recent advances in cold-atom platforms have made real-time dynamics accessible, renewing interest in the motion of superfluid vortices in two-dimensional domains. Here we show that…
A quantum Monte Carlo based density functional for Dysprosium dipolar system
Raúl Bombín, Viktor Cikojević, Ferran Mazzanti +1
We present a quantum Monte Carlo based density functional to describe droplet formation and supersolidity in dipolar systems. The usual Lee-Huang-Yang term, accounting for quantum…
Universal composite boson formation in strongly interacting one-dimensional fermionic systems
Francesc Sabater, Abel Rojo-Francàs, Grigori E. Astrakharchik +1
Attractive -wave one-dimensional fermions are studied in the fermionic Tonks-Girardeau regime in which the diagonal properties are shared with those of an ideal Bose gas. We stu…
